17 TPA-AA-202 Accessory Cable Kit
Caution The radio produces a specific audio level at the max-
imum rated power. It is the sole responsibility of the
end-user to ensure applicability and compliance
with the relevant legal regulations defining the noise
level an individual can be subjected to.
The TPA-AA-202 accessory cable kit is used to connect
external third-party accessories, such as speaker
microphones and headsets, to the accessory connector at
the rear of the radio.
17.1 Connecting an Accessory
1. Verify that your accessory is compatible with the accessory connector,
refer to Table 17.1.
2. When connecting an accessory, make sure it meets the following
specifications:
■ speaker impedance: 32Ω (16Ω min.)
■ speaker power: 0.25W
rms
(min.)
■ microphone: electret, approximately 1kΩ
■ PTT switch: not in series with microphone.
Note If your accessory has a PTT switch in series with the microphone,
the accessory cannot be used. The PTT needs to be a separate sig-

not be multiplexed on any other signal.
